RRC losing water

[Markh]

Am at a bit of a loss, my 1993 RRC 3.9 is losing about 500ml of water every 12/1500 miles, no visable signs of a leak, oil is clear, my garage carried out a test which showed no combusion gase's in the cooling system, car does not over heat , temp stays rock steady on normal (even gong through the middle of London last week), I have changed the expansion tank cap as I though there was a leak there. system is holding pressure overnight.

any thoughts

I could do, but would rather find teh problem than bodge it, bloody stuff is going somewhere?

It could be the pressure cap on the expansion tank passing and letting water out of the overflow.Try a New cap cheap enough.

Remove the carpet in the front drivers side footwell. If it is wet / damp on the underside it means the heater matrix or pipework has a fracture/corroded and is leaking coolant. A common problem on the classic.
